For all models the Maximum System voltage for IEC standards is 1000V and
maximum series fuse is 15A. For models not shown here, please contact SunPower
technical support or visit www.sunpower.com. Electrical parameters are measured at
Standard Test Conditions (STC).
DANGER! Module interconnection cables pass direct current (dc) and
are sources of voltage when the module is under load and when it is
exposed to light. Direct current can arc across gaps and may cause
injury or death if improper connection or disconnection is made; or
if contact is made with module leads that are frayed or torn. Do not
connect or disconnect modules when a current source is energizing
the conductors. Modules may contain high voltage when
interconnected with other modules.
IMPORTANT! Please read this manual in its entirety before
installing, wiring, or using this product in any way. Failure to comply
with these instructions will invalidate the SunPower Limited
Warranty for PV Modules.

Bypass diodes are factory installed and are not user replaceable. The diode
configuration for 96 cell modules is 2 diodes for 2 strings of 24 cells in series, plus
one diode for a single string of 48 cells in series. For 128 cell modules, the
configuration is 2 diodes installed for 2 strings of 32 cell in series, plus one diode
for a single string of 64 cells in series. The diodes are one of the following ratings;
1. Schottky type, 15A, 45 Peak Inverse Voltage (PIV) for 96 cell modules.
2. Schottky type, 20A, 45 PIV for 128 cell modules.
3. Schottky type, 20A, 100 PIV for 96 and 128 cell modules.
4.0 Electrical Connections
Modules may be connected in series or parallel to achieve the desired electrical
output provided certain conditions are met.
SunPower recommends using the same brand/type of dc ‘home run’ connector as
on the module it connects to. This helps insure compatibility.
4.1 Equipment Grounding
To reduce the possibility of electrical shock, ground the frame of the module or
array per NEC before wiring the circuit. In order to install in accordance with their
UL Listing, SunPower modules must be grounded using grounding hardware that
meets requirements for grounding systems in UL 467, UL 1703, or UL 1741; on
anodized aluminum frames. SunPower recommends using one of the following
methods of grounding the module frame. In addition, to avoid corrosion due to
the use of dissimilar metals SunPower recommends stainless steel between
copper and aluminum. For the Generation 5 (G5) frame, only methods 1 and 2
apply.
1) Attach a lay-in lug (Ilsco GBL-4DBT, Burndy CL50-DB-T or Tyco Solklip 1954381-
2) to one of the grounding holes on the module frame, and attach the
ground conductor to the lug. Use stainless steel hardware (bolt, washers,
and nut). Use an external-tooth star washer between the lug and the
module frame in order to pierce the anodizing and establish electrical
contact with the aluminum frame. The assembly must end with a nut that’s
torqued to 20–25 in-lb (for a #10-32 bolt). A lock washer or other locking
mechanism is required to maintain tension between the bolt and the
assembly. The conductor must be attached to the ground lug using the lug’s
set screw. Refer to NEC 690.
2) SunPower modules may also be grounded through the use of SunPower IFF
clips which are UL Listed (1703 and 1741). IFF clip torque value is 35–45 in-
lbs for a 1/4-20 or M6 bolt, but may be higher in specific applications.
When using IFF clips, the module mounting system must be grounded as
per NEC 250.
3) SunPower modules may also be grounded through the use of an Everest Solar
Systems Mid or End Clamp assembly. The assembly consists of a stainless
M-K2 slot nut, WEEB KMC grounding clip, Everest Solar aluminum End or
Mid clamp, stainless M8 bolt and stainless Belleville lock washer. The WEEB
is placed under the bottom edge of the module and the clamp is placed on
the top edge of the module. The bolt captures the Bellville washer, the
clamp, the WEEB and the M-K2 nut and must be torqued to min. 10.3 ft-lbs.
This method is valid when the modules are being secured to Everest Solar
aluminum Dome D1000, Dome S1000 or Dome SD mounting components. A
SunPower IFF clip #509206 may be substituted for the actual Everest Mid
Clamp itself, but only when the modules are being installed using
SunPower’s D10 or S10 product; with 72- and 96-cell modules only. The IFF
clip must be torqued to 35-45 in-lbs. When the end clamp is used for
securing the last module in a row, the last module must be separately
grounded when servicing the adjacent module.
Note: Method 4 is evaluated to UL 1703 by ETL. As such, the use of these devices
is not considered part of the UL Listing of these modules.
4) If the Unirac SOLARMOUNT system is used for mounting the modules,
grounding is achieved using either a BURNDY Wiley WEEB-UMC or WEEB-
UGC-1 grounding clip in combination with Unirac’s Mid or End clamps and
1/4-20 bolt and flanged nut, torqued to 120 in-lbs. If the Solarmount-I
system is used grounding is achieved with the UniRac UGC-2 grounding clips
in combination with UniRac’s Mid or End clamps and Sliders with a 1/4-20
bolt and flanged nut torqued to 120 in-lbs.
Note: Method 5 was evaluated to UL 2703 by TUV. As such, the use of these
devices is not considered part of the UL Listing of these modules.
5) SunPower modules may also be grounded using a WEEB-9.5NL ground clip in
between the module and supporting structure. This combination is secured
with a 1/4″stainless steel rivet or a 1/4-20 by 3/4″zinc-plated bolt with
zinc-plated K-nut torqued to min. 6 ft-lbs to secure the module to minimum
12 ga. G90 coated steel or Z-purlin, either painted or unpainted. The WEEB-
9.5NL is for single use only.
6) Other grounding methods may be used in conjunction with a module mounting
system tested to UL2703. For these installations, the SunPower module and
frame style must be tested and part of the instructions for the listed
mounting product. The SunPower module must be installed in accordance
with these instructions as well as the mounting system’s listed instructions.
7) SunPower G5-frame modules may be grounded through the use of an
InvisiMount™ mid clamp that bonds the module frame to the InvisiMount™
rail. InvisiMount™ rail sections must be bonded and connected to a
grounding conductor using methods and materials specified in the
InvisiMount™ manual.
When using methods 2, 3, 4, 5 or 6 the module mounting structure must be
grounded as per NEC 250. To ensure system safety and structural integrity, strict
adherence to application-specific SunPower documentation is required.
4.2 System Grounding
Review the Table 2 below for the proper grounding techniques for the installation
of your particular SunPower modules.

IMPORTANT! For optimal performance, SunPower modules listed above
as needing positive grounding must be configured as described. Failure to
comply with this requirement will reduce system performance and
invalidate SunPower’s Limited Power Warranty for PV Modules.
5.0 Module Mounting
The SunPower Limited Warranty for PV Modules is contingent upon modules
being mounted in accordance with the requirements described in this section.
5.1 Site Considerations
SunPower modules should only be mounted in locations that meet the following
requirements:
Operating Temperature: All SunPower modules must only be mounted in
environments that ensure they will operate within the following temperatures:
Operating Temperature range
-40°C to +85 °C
-40°F to +185 °F
Care should be taken to provide ventilation behind or underneath the modules,
especially in hot environments.
Design Strength: SunPower modules are designed to meet a maximum positive
(or up/down, e.g. wind) and negative (or downward, e.g. static or snow load)
design pressure described in the Table 3. Design strength of 2400Pa wind load
corresponds approximately to a wind speed of 130 km/h (approximately ±800 Pa,
per IEC reference) with a safety factor of 3 for gusty winds. Modules have also
been evaluated by UL for a maximum negative or positive design load of 30 psf.
Figure 1: Mounting locations for SunPower Modules shows where to mount to
the module frame. Table 3 defines mounting options, attachment locations and
resulting load rating achieved for each module configuration.

Excluded Operating Environments
Certain operating environments are not recommended for SunPower modules,
and are excluded from the SunPower Limited Warranty.
5.2 Mounting Configurations
Modules integrated into or mounted over a roofing system must be mounted
over a fire-resistant roof covering rated for the application. Modules may be
mounted at any angle, from horizontal to vertical. To reduce soiling, modules
should be mounted at a minimum of 10 degrees.
Residential (black) module frames have two profile types, G3 and G5. Commercial
(silver) module frames have permanently attached stacking pins. Mounting
system hardware used with commercial modules must account for the presence
of these stacking pins. Mechanical specifications for modules are shown in Table
4.
In order to prevent water from entering the junction box, which could present a
safety hazard, modules should be oriented with the junction box in the
uppermost position and not be mounted such that the cell faces downward (e.g.
on a tracking structure that positions the modules with the junction box facing
skyward during sleep mode).
For 128-cell modules a minimum of 4″ of clearance between the module frames
and the structure (or grade) is required; for all other modules a minimum of 1.5″
of clearance is required.
The module is only UL Listed for use when its factory frame is fully intact. Do not
remove or alter the module frame, and do not create additional mounting holes
because doing so may compromise the integrity of the frame.
Modules may be mounted using the following methods only:
1) Frame Holes: Secure the module to the structure using the factory
mounting holes. Four 1/4″stainless steel bolts, with nuts, washers, and lock
washers are recommended per module; tightened to a min. torque of 10 in-
lbs. Refer to Table 4 for the module dimensions and hole locations. This
method has been certified by a third-party organization according to UL
1703. For frame hole mounting, modules must be secured using the holes
located at 322mm from the short end of the module for 72 and 96 cell
modules and 433mm from the end of the module for 128 cell modules. For
carport installations the supporting structure has been pre-drilled. For 128
cell modules for carport assembly, modules must be secured using only the
holes located 433mm from the ends of the module and hardware described
above in Section 4.1, Item 5. See Figure 2 for carport assembly details.
2) Clamps or Clips: Mount the module with the IFF clips on the longer sides of
the module. The centerline of the clips must be 2-16” for G5 frame (6–15″
for G3 frame) from the corner of the module. Ensure that the clamps are of
sufficient strength to allow for the maximum design pressure of the
module. The IFF clip hardware must be tightened to a torque of 35-45 in-
lbs.
3) End Mount: End mounting is the attachment of the shorter side of the
module frame to a supporting rail using IFF clips tightened to a torque of
35-45 in-lbs. The centerline of the clips must be 2-10” from the corner of
the module. The end-mounting rail and clips or clamps must be of sufficient
strength to allow for the maximum design pressure of the module. Verify
this capacity before installation.
4) Everest Solar Mounting System: An Everest Solar Mid or End Clamp can be
used to secure the shorter ends of the module. When using Everest Solar
mounting hardware. The Everest Solar stainless M-K2 Slot nut is placed in
the channel of the aluminum Dome D1000, Dome S1000 or Dome SD
mounting component. The WEEB KMC grounding clip is placed under the
bottom edge of the module. The Mid or End clamp is placed over the top
edge of the module frame and secured to the M-K2 slot nut using a stainless
M8 bolt and stainless Belleville washer tightened to a min. of 10.3 ft-lbs. A
SunPower IFF clip #509206 may be substituted for the Everest Mid Clamp,
but only when the modules are being installed using SunPower’s D10 or S10
product. Two clamps must be used on each of the shorter ends of the
module; on 72- and 96-cell modules mounted in landscape orientation only.
5) SunPower-specified or SunPower-supplied mounting systems: Mount
modules with strict adherence to SunPower documentation, using
hardware systems supplied by or specified by SunPower.
5.3 Module Handling
Use gloves when handling modules. The module glass is sensitive to oils and
abrasive surfaces, which may lead to scratches and irregular soiling. Do not place
modules such that the glass comes in contact with abrasive surfaces, and
minimize any contact with the glass in general. Do not place anything on the
modules, even for a moment. Remove any fingerprints by washing the module
glass as described in Section 6.0 below.
6.0 Maintenance and Cleaning
Trained SunPower dealer or trained SunPower support personnel should inspect
all modules annually for safe electrical connections, sound mechanical
connections, and freedom from corrosion.
Periodic cleaning of module glass has resulted in improved performance levels,
especially in regions with low levels of annual precipitation; therefore SunPower
recommends periodic cleaning of the modules.
To clean a module, wash its glass surface with potable, non-heated water.
Normal water pressure is adequate, but pressurized water (up to 1500 psi) may
be used. Some fingerprints, stains, or accumulations of dirt on the glass may be
removed with over-the-counter glass cleaners (such as Windex®or equivalent), or
with a 3% soap-and-water solution. For smaller systems, wet the module glass
with the solution, let it stand for five minutes, and then wet them again and use a
soft sponge or seamless cloth to wipe the glass surface in a circular motion. For
large systems, wet the modules with the cleaning solution, let them stand for five
minutes, and then rinse them with high-pressure water or a soft squeegee. Do
not use harsh industrial-strength cleaning materials such as scouring powder,
steel wool, scrapers, blades, or other sharp instruments to clean the module
glass. Use of such materials will void the product warranty.
